Handle NPD during cluster upgrade.
Generate NPD token during upgrade.
I could not fully verify this change because of https://github.com/kubernetes/kubernetes/issues/42199. However, at least I tried upgrade master, and the corresponding environment variables are correctly generated.

Remove VCenterPort from vsphere cloud provider.
**What this PR does / why we need it**:
Address a bug inside vsphere cloud provider when a port number other than 443 is specified inside the config file.
The url which is used for communicating with govmomi should not include port number.
A port number other than 443 will result in 404 error.
VCenterPort stays in VSphereConfig structure for backward compatibility.

We talked about dropping docker 1.9.x support for a while. I just realized that we haven't really done it yet.
```release-note
Dropped the support for docker 1.9.x and the belows.

Implement automated downgrade testing.
Node version cannot be higher than the master version, so we must
switch the node version first. Also, we must use the upgrade script
from the appropriate version for GCE.

Create DefaultPodDeletionTimeout for e2e tests
In our e2e and e2e_node tests, we had a number of different timeouts for deletion.
Recent changes to the way deletion works (#41644, #41456) have resulted in some timeouts in e2e tests. #42661 was the most recent fix for this.
Most of these tests are not meant to test pod deletion latency, but rather just to clean up pods after a test is finished.
For this reason, we should change all these tests to use a standard, fairly high timeout for deletion.

Don't wait for the final deletion of pod
The final deletion of the pod depends on kubelet and other components operating correctly. The purpose of this e2e test is verifying the clientset can handle deleteOptions correctly, so waiting for the deletionTimestamp and deletionGraceperiod get set is good enough.
In the long run, we should move this set of e2e tests to integration tests.

add debugging to the client watch test
Adds debugging information for https://github.com/kubernetes/kubernetes/issues/42724. I suspect that the watch is closing early, but I'd like proof before I consider things like retrying the list and doing another watch to observe the delete. I'm not even sure that would satisfy the test
It seems like a flaky way to build the test. Why wouldn't we delete non-gracefully?

@wojtek-t saw you just hit this if you wanted to take a quick look at the debugging I added.

Ensure a fixed godep version in hack/*-godep*.sh

Fixed potential OutOfSync of nodeInfo.
The cloned NodeInfo still share the same resource objects in cache; it may make `requestedResource` and Pods OutOfSync, for example, if the pod was deleted, the `requestedResource` is updated by Pods are not in cloned info. Found this when investigating #32531 , but seems not the root cause, as nodeInfo are readonly in predicts & priorities.
Sample codes for `&(*)`:
```
package main
import (
"fmt"
)
type Resource struct {
A int
}
type Node struct {
Res *Resource
}
func main() {
r1 := &Resource { A:10 }
n1 := &Node{Res: r1}
r2 := &(*n1.Res)
r2.A = 11
fmt.Printf("%t, %d %d\n", r1==r2, r1, r2)
}
```
Output:
```
true, &{11} &{11}
```

Create EnsureExists class addons before Reconcile class addons
From #42757.
The addon-manager creates "Reconcile" class addons before creates "EnsureExists" class addons, which is not the best order. The "EnsureExists" class addons tend to be some default configurations like `default-storage-class` and `default kube-dns ConfigMap` (being added in #42757), and we would like to have these default configurations created before other addons are created.

dockershim: Fix the race condition in ListPodSandbox
In ListPodSandbox(), we
1. List all sandbox docker containers
2. List all sandbox checkpoints. If the checkpoint does not have a
corresponding container in (1), we return partial result based on
the checkpoint.
The problem is that new PodSandboxes can be created between step (1) and
(2). In those cases, we will see the checkpoints, but not the sandbox
containers. This leads to strange behavior because the partial result
from the checkpoint does not include some critical information. For
example, the creation timestamp'd be zero, and that would cause kubelet's
garbage collector to immediately remove the sandbox.
This change fixes that by getting the list of checkpoints before listing
all the containers (since in RunPodSandbox we create them in the reverse
order).

Adds default kube-dns configmap
From #42746.
Using 1.4 kubelet with 1.6 master is causing upgrade test failures. Because kubelet doesn't understand optional configmaps and there is no kube-dns configmap exist, kubelet will crash.
This PR adds an empty kube-dns configmap as an "EnsureExists" class addon for fixing that.
Note: The addon-manager creates "Reconcile" class addons before creates "EnsureExists" class addons, which is not the order we want. I will soon have another PR to reverse this order.
